District Cooling Feasibility Study: Tampines Central Distributed District Cooling
Network
In highly developed cities like Singapore, majority of land has been built up and individual building owners are already equipped with their own chiller plants. With Distributed District Cooling (DDC) network – an interconnected, centralised cooling system – existing towns and districts may now be able to enjoy a more sustainable way to cool.
To find out the sustainable impact of this innovative approach, we partnered Temasek on a feasibility study involving 14 buildings in Tampines Central, and was supported by the Tampines Group Representation Constituency (GRC) and the Ministry of Sustainability and the Environment (MSE).
The results are promising. In one year, the DDC network could potentially achieve:
• A 17% reduction in energy consumption - enough to power 1,665 three-room HDB households for a year
• A 18% fall in carbon emissions from both energy savings and refrigerant reduction – equivalent to removing 2,250 cars from roads per year
• S$4.3 million in annual economic value from energy, equipment replacement and maintenance cost savings, as well as potential earnings from leasing out freed-up chiller plant space
